I have my auto and $1M umbrella from geico. Since I am selling my house and will not have an officical abode for awhile, I called to find out if I will lose my umbrella policy since I will no longer have the supposedly required $300k liability from my home insurance and I don't need any rentor's insurance yet. I was told, I would not lose my umbrella policy. This means is that any lawsuit from an outside auto or non-auto related incident will be covered by 100% of my umbrella coverage while any lawsuit from a home related incident will be covered by $700k (less $300k deductible) umbrella coverage.
